How Sunscreen Can Trigger Breakouts in Some Skin Types
Sunscreen protects your skin from harmful UV rays, but for certain skin types, it can lead to unexpected breakouts. This happens mainly because some formulas clog pores or create conditions that trap oil and bacteria inside them.
Acne starts when pores get blocked by excess oil, dead skin cells, and bacteria. People with oily or acne-prone skin produce more sebum, the natural oil that keeps skin moist. When something extra blocks those pores, pimples form more easily.
Heavy mineral sunscreens often contain oils that sit thick on the skin. These can coat pores and prevent them from breathing, leading to clogs and breakouts. Chemical sunscreens absorb UV light and convert it to heat. That warmth builds up inside pores, making oil thicker and encouraging bacteria growth, which sparks acne.
Not everyone reacts this way. Dry skin types might handle richer creams fine, but oily or combination skin fares worse with greasy textures. Summer heat and sweat make it tougher, as they boost oil production and mix with sunscreen residue.
Look for clues on labels. Words like “non-comedogenic” mean the product is tested not to clog pores. Gel-based or water-based sunscreens feel light and absorb fast without residue. Mineral options with zinc oxide or titanium dioxide work if they are matte and oil-free.
Switching products helps many people. Start with a small SPF, like 30, and patch test on your jawline first. Cleanse gently twice a day to remove buildup, especially after sweating. Over time, your skin adjusts to better formulas.
